The Accordian Files is a complete RPG that pits the forces of accord (the player characters) against the forces of discord (run by the Discord Master). Three books comprise the system: The Player’s Book, The Discord Master’s Book, and the introductory adventure, The Ghost in the Washing Machine. All three PDFs fit on 24 pages, or you can use the PocketMod versions to fit the entire game on three sheets of paper folded up small enough to fit in your back or shirt pocket. Here’re the linkies:
